Reference Guide for the Model RT328 and Model RH348 ISDN Routers
System Maintenance 9-3
Figure 9-1 illustrates two packet examples shown on Menu 24.1. The first is an ICMP Ping packet
(Type: IP) triggering the call, and the second is a SAP broadcast packet (Type: RAW). With this
information, you can determine the source IP address (C0 44 87 22) of the packet or the source
MAC address (00 40 95 90 04 B9) of the packet.
Figure 9-1. Packet Examples
Terminal Baud Rate
You can change the baud rate of the serial Manager connection through Menu 24.2, Terminal Baud
Rate. The router supports 9600 (default), 19200, and 38400 bits per second (bps) for the RS-232
connection.
To change the rate, toggle the selection using the space bar. When the desired rate is shown, press
[Enter]. You are given the opportunity to change the baud rate of your terminal before continuing.
Country Code This field displays the one-byte country code value (in decimal notation). For example,
255 indicates North America.
LAN Packet Which
Triggered Last Call
This field displays the first 48 octets of the LAN packet that triggered the last outgoing
call. Two types of packets are displayed: IP and RAW. By viewing the packet
information, you can determine which station has sent a packet to cause the router to
make an outgoing call.
